Olsen et al., 2018: 140 (a summary was given by Oosterbroek et al., 2007, citing various authors: a semi-aquatic species; for Northwest USA (NY and New England) the following habitats have been listed: dryer woods above swamp, Sphagnum bog, Arborvitae swamp, very old bogs, swales, in Hellebore patches; habitats for Far East Russia are open Fir-Larch [Abies-Larx] woodland (Sakhalin) and mixed forests (Kuril Is); the period of flight is july-september; see table 1 for habitat information of the Norwegian locality(ties)). Habitat. Kolcsar et al., 2025: 13 (the larvae are semi-aquatic and are known to occur in various wet habitats (Young & Gelhaus 2000), in swamps, bogs, swales, and woodland near swamps in America (Alexander 1924a, 1925, 1927, 1936, Oosterbroek et al. 2007), as well as in woodland habitats in the Far East of Russia (Savchenko & Krivolutskaya 1976); in Europe, the species is found in similar habitats, in Sweden collected by the author in a pasture and along a small stream with Carex dominated vegetation).

Oosterbroek et al., 2007: 21 (a semi-aquatic species (Young and Gelhaus, 2000); for the Northwest USA (NY and New England) the following habitats have been listed: dryer woods above swamp, Sphagnum bog, Arborvitae swamp, very old bogs, swales, in Hellebore patches (Alexander, 1924l, 1925i, 1927c, 1936p); habitats for far eastern Russia are open Fir-Larch woodland (Sakhalin) and mixed forests (Kuril Is) (Savchenko & Krivolutskaya, 1976).

Europe Distribution. Kolcsar et al., 2025: 12 (the species should be regarded as an invasive non-native species in Europe; it remains unknown from where and how the species was introduced to Europe, as well as what kind of impact it may have on local ecosystems; furthermore, the species is listed as an introduced species in North America (Simpson et al. 2022), with Europe marked as the origin of the species; however, this seems to be a mistake, as the first American records of the species date back to the early 1900s and the first European records from only a few years ago; the species recently has exhibited rapid expansion in the southern part of Fennoscandia over yhe last few years and although the males have a spectacular terminalia, which makes them easily distinguishable from other European Ormosia species, there are no historical records of the species from Fennoscandia).
